Question

M1卡的存取控制4个字节: FF 87 80 95 表示什么意思?                     FF 07 80 69 又表示什么意思?

Answer 1

一、IC卡扇区
扇区 块
0 0
1

三、存取控制结构
Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0
Byte 6 C2X3_b C2X2_b C2X1_b C2X0_b C1X3_b C1X2_b C1X1_b C1X0_b
Byte 7 C1X3 C1X2 C1X1 C1X0 C3X3_b C3X2_b C3X1_b C3X0_b
Byte 8 C3X3 C3X2 C3X1 C3X0 C2X3 C2X2 C2X1 C2X0
Byte 9 BX7 BX6 BX5 BX4 BX3 BX2 BX1 BX0
_b：取反，如C2X3_b即C2X3取反
X：表示第几块
C表示控制位
B表示备用位
四、对块3的存取控制
所有16个扇区均适用
C1X3 C2X3 C3X3 密码A 密码A 存取控制 存取控制 密码B 密码B
Read Write Read Write Read Write
0 0 0 Never KEYA|B KEYA|B Never KEYA|B KEYA|B
0 1 0 Never Never KEYA|B Never KEYA|B Never
1 0 0 Never KEYB KEYA|B Never Never KEYB
1 1 0 Never Never KEYA|B Never Never Never
0 0 1 Never KEYA|B KEYA|B KEYA|B KEYA|B KEYA|B
0 1 1 Never KEYB KEYA|B KEYB Never KEYB
1 0 1 Never Never KEYA|B KEYB Never Never
1 1 1 Never Never KEYA|B Never Never Never
KEYA|B 表示密码A或密码B；Never表示没有条件实现。
五、对数据块的存取控制
所有16个扇区的块0、1、2均适用，0扇区有例外，i=0、1、2
C1Xi C2Xi C3Xi Read Write Increment Decr,Transfer,restore
0 0 0 KEYA|B KEYA|B KEYA|B KEYA|B
0 1 0 KEYA|B Never Never Never
1 0 0 KEYA|B KEYB Never Never
1 1 0 KEYA|B KEYB KEYB KEYA|B
0 0 1 KEYA|B Never Never KEYA|B
0 1 1 KEYB KEYB Never Never
1 0 1 KEYB Never Never Never
1 1 1 Never Never Never Never
六、存取控制举例
块3的初始化值为：
KeyA=A0、A1、a2、A3、A4、A5
控制块=FF、07、80、69
KeyB=B0、B1、B2、B3、B4、B5
字节 Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0 权限
Byte 6 C2X3_b C2X2_b C2X1_b C2X0_b C1X3_b C1X2_b C1X1_b C1X0_b FF
1 1 1 1 1 1 1 1
Byte 7 C1X3 C1X2 C1X1 C1X0 C3X3_b C3X2_b C3X1_b C3X0_b 07
0 0 0 0 0 1 1 1
Byte 8 C3X3 C3X2 C3X1 C3X0 C2X3 C2X2 C2X1 C2X0 80
1 0 0 0 0 0 0 0
Byte 9 BX7 BX6 BX5 BX4 BX3 BX2 BX1 BX0 69
0 1 1 0 1 0 0 1
得出存取控制位如下：块
0 C1X0 C2X0 C3X0
0 0 0
1 C1X1 C2X1 C3X1
0 0 0
2 C1X2 C2X2 C3X2
0 0 0
3 C1X3 C2X3 C3X3
0 0 1
16 a0-a5 47 ff-ff 文件读写方式KeyB=B0、B1、B2、B3、B4、B5
字节 Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0 权限
Byte 6 C2X3_b C2X2_b C2X1_b C2X0_b C1X3_b C1X2_b C1X1_b C1X0_b 08
0 0 0 0 1 0 0 0
Byte 7 C1X3 C1X2 C1X1 C1X0 C3X3_b C3X2_b C3X1_b C3X0_b 77
0 1 1 1 0 1 1 1
Byte 8 C3X3 C3X2 C3X1 C3X0 C2X3 C2X2 C2X1 C2X0 8f
1 0 0 0 1 1 1 1
Byte 9 BX7 BX6 BX5 BX4 BX3 BX2 BX1 BX0 00
0 0 0 0 0 0 0 0
得出存取控制位如下：块
0 C1X0 C2X0 C3X0
1 1 0
1 C1X1 C2X1 C3X1
1 1 0
2 C1X2 C2X2 C3X2
1 1 0
3 C1X3 C2X3 C3X3
0 1 1
